• ABSTRACT
    • In order to assess acetabular joint congruity and postoperative reconstructions, a study was undertaken to evaluate the use of coronal and sagittal reconstruction of transaxial CT scans. The 28 acetabular fractures evaluated included 10 posterior wall, 11 transverse, 6 associated both column, and 1 nonclassifiable medial wall fracture. In 7 cases the surgical approach was modified from the original preoperative plan based on the coronal and sagittal CT reconstruction results. In 2 other cases associated both column fractures were treated nonoperatively based upon the coronal and sagittal CT reconstruction results. In 2 cases intraarticular fracture fragments were shown to be larger than expected from the original studies. In all cases of marginal impaction (N = 10) coronal and sagittal CT reconstruction showed that the fragments were larger than they appeared to be on the transaxial CT scan. Coronal and sagittal CT reconstruction provided more detailed evaluations of these complex fractures than other studies.
